When you're choosing a steel pipe, understanding the distinction between ERW (Electric Resistance Welded) and CEW (Cold Drawn Electric Welded) pipe is crucial. While both are used in many industries, they aren't the same. Simply put, CEW pipe starts as an ERW pipe and then undergoes an additional process to enhance its properties. Let's break down what each type is and which one is right for your project.
